Testosterone boosters? Which ones? Most are crap. Try to get enough vitamin D, zinc, and magnesium to regulate your testosterone levels. The only testosterone boosters that might actually work are Ashwagandha and DHEA and maybe DAA.
Your levels of oestrogen do not effect your levels of testosterone so your argument is faulty, there is so much evidence to show soy increases levels of eostrogen in blood larger than normal levels
